COCKLE-SE ED SEPARATOR.

To all whom, it 'nuty concern Be it-kuown that I, RICHARD BESON W'IL SON, Jr., of McLe-ansborough, in the county of Hamilton and State of lllinois, have invented a new and useful Improvement in Cockle-Seed Separators, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings. forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a longitudinal section of my improvemcntdaken through the line x00, Fig. 2. Fig. 2 is a plan view ofthe same, part ofthe tip- 1) r sieve being broken away. Fig. 3 is a sectional end elevation ofthe sa-ine,'taken through the line y 3 Fig. 1, part. of the frame being shown in end view as indicated by the line 5 Fig. 1. Fig. 4 is a sectional end elevation of the same, taken through the line to w, Fig. l.

The object of this invention is to facilitate the separation of cockle seedfrom wheat and promote thoroughness in such separation.

The invention relates to a cookie-seed separator constructed with a series of inclined sieves. sieve boards, 'and discha ge spouts and chute, arranged in avihrating shoe, a cylinder covered with perforated sheet metal, and a driving mechanism. To the shoe are attached angular slides. which rest upon inclined bars attached to the frame, and placed parallel with the sieves, so that the said shoe will he made to move parallel with the sieve.

The shoe is connected by rods with eccentrics formed upon the driving-shaft, so thatthe said shoe will be vibrated from the said drivingshaft. The cylinder, covered with perforated sheet metal, is placed at the side of the spout that receives the cockle-seed from the sieves, to remove the said cockle-seed from the ma- Tlie reeeivingsieve is kept clean by brushes attached to endless hands passed around wheels attached to shafts jonrnaled to the sides of the shoe, and driven by a pawl attached to the frame. and engaging with a ratchet-wheel attached to one of the shafts, as will he hereinafter fully described.

A represents the frame of the machine; 13, the shoe or shaker, to the sides of which are attached the upper arms of angle-irons O, the

clination as the sieves, so that the movement of the shoe B will be parallel with the movement of the grain upon the said sieves.

To the front end of the shoe .8 are hinged the ends of two short rods, E, the other ends of which are pivoted to eccentrics F, formed upon the shaft G. The shaft G revolves in bearings in the front of the frame A, and to one of its ends is attached a pulley, H, to receive a driving belt from any convenient power.

To the upper edge of the front of the shoe B is attached a transverse spout or apron, I, to receive the grain from a feed-hopper (not shownin the drawings) and deliver it to the upper sieve, J, which has a slight downward inclination toward the tail end of the machine.

The sieve J is made of such a fineness of mesh that the large kernels of wheat cannot pass through the meshes, but will slide down the said sieve and fall from its lower end into the inclined transverse spout K, from which they pass into the chute L. The eockle-see-d and the small kernels of wheat that pass through the sieve J fall upon the sieve-board M, attached to the shoe B, with a downward inclination toward the head of the machine. The sieve-board M does not extend quite to the head of the shoe B, so that the small kernels of wheat and the cockle'seed will fall from its lower end upon the head end of the sieve J. A part of the small'kernels of wheat slide down the sieve J and pass from its lower end to the sieveboard M, down which they slide,

and fall from its lower end into the inc ined' spout K, and pass thence into the chute L. The part of the small kernels of wheat and the Cockle-seed that pa=s through the sieve J fall upon the sieve-board M, down which they slide to the upper end of the sieve J. Apart of the small kernels of wheat left with the cockle-seed slide down the sieve J fall from its lower end into the inclined spout K, and pass thenceinto the chute L. The part of the small kernels of wheat and the cookie-seed that pass through the sieve J fall upon the sieve-board M slide down the said sieveboard toward the head of the shoe B, and fall upon the head end of the sieve J'. A part of lower arms of which rest and slide upon bars l the small kernels of wheat still left with the cookie-seed slide down the sieve J to the sievel eled gear-wheel '1', attached to the lower part board M, from the lower edge of which they 1 of the vertical shalt U.

The shaft U revolves fall upon thelower partof the sieve-board M, l in hearings in the frame A, and to its upper fall from its lower edge to the sieve J", and

Apart of the small kernels of wheat still left with the cockle-seed slide down the sieve J to the sieve-board M, from the lower edge of which they fall upon the sieve J", pass thence into the spout-1i", and are discharged into the chute T1- The part of the small kernels of wheat and the cockle seed that pass through the sieve J fall upon the sieve-board M from the lower edge of which they pass to the sieve J" down which a part of the small kernels of wheat slide into the spout K and pass thence to the chute L. The small kernels of heat and the cookie seed that pass through the sieve J fall into the spout N, and tall from its lower end at the head of the shoe B into the head end ol" the spout O. One side of the spout O is formed by the cylinder 1, which is covered with perforated sheet metal (Q, the. pertorations being made of sucll a size as to receive cockle-sccd, but not kernels of wheat. The pcrl'orali d sheet metal Q carries the eockle-seed over the cylinder P. and allows it to fall into the hopper It, placed below the said cylinder P, and from the discharge openingofwhichthesaid cockleseed fall into a receiver placed elow the machine. Any small kernels of wheat that may enter the spout 0 pass down the said spout along the side of the perforated covering Q of t eeylinder 1 and tall intothe hoppei at. that reccivesthe wheat ll'Ulll the chute L. and from tl.e lischarge-opening of the said hopper t the heat, wholly l'reed ll'Olll cockle seed, falls into some suitablereceher placed beneath the machine. 'lhejournals of the cylinder P revolvein bearingsattached to the frame A, and to the journal of the head end of the said cylinder is attached abeveled gear-wheel, S. the teeth of which mesh into the teeth of the bevother suitable material.

end is attachct'l, a beveled gearwheel, V, the teeth 0t which mesh into the teeth ot the beveled gear-wheel W, attached to the driving shaft G.

To the sides 01' the shoe ll, :1 little below the sieve J, are journaled two or more shafts, X. to the end parts of each of which are attached wheels Y.

Around the wheels Y pass two endless belts, Z, to which are attached brushes (1, ol'irubber or The brushes a more along the lower side of the sieve J, and thus keep the said sieve clear.

To a journal of one of the shafts X is attached a ratchet-wheel, b, with the teeth of which engages a spring-pawl, 0, attached to the frame A, so that the said ralchct-whcel will be turned the space of one tooth at each rearward movement of the shoe B, causing the brushes (0 to move slowly along the under side of the sieve J.
